Sounds like over-heating or the dGPU is dying

Make sure there isn't dust build up in the vents

Check your connection ports for micro-shavings or threads of debris. Those magnetized connectors also attract such stuff. Happened to me. Totally shut down display on my Surface Book 2. Thought it was gone. Found a tiny metallic thread.
